help how do i maximize my space?? 😭

hi everyone! i just moved to a new apartment and my room is a bit small … i tried to make a somewhat accurate rendering of my room so i could play with placements but im having a tough time trying to figure out where to put my bed which would prob be a TWIN and i’d also like to fit a desk in there and a full length mirror . i also want to feng shui it so would not want the mirror to face my bed and what not . any ideas on how i can best maximize the space i have? thanks so much in advance! 🤍
